Thanks for all of the reviews! Sorry for the random changes of plot, it started out as a one-shot and has now developed into the story of chemistry kitten running amok in Avengers Tower.

*If you have a suggestion for a change in title please message me because the original one doesn't really fit now :) I am also open to prompts for future chapters for this story or even a whole new story altogether!

Disclaimer: None of the Avengers belong to me...yet. (Except Robert. He is mine.)

World War III

Robert's routine had become a bore. The lab had been slow lately since everything was away being analyzed, and he had already gone through all of the interesting reading material down there. His boredom had lead to some new habits that in some eyes, could be viewed as destructive. Some eyes meaning all of the humans eyes. Robert had taken up scratching, everything.

The living room couch was in tatters, Tony's bed was down to only one pillow, the drapes looked like they were out of an old horror film, it had to stop. Then the worst thing was brought up; declawing.

It was Natasha who had suggested it.

"I just don't see what the big deal is, cat's are declawed all the time!"

"It's barbaric!"

"I agree with Tony, the practice of declawing is not just removing the nail, it destroys the bone as well." Bruce added.

"Really? Well what else is there to do?"

"I don't know. We could try getting him some new toys"

"We'll see."

The conversation ended there. Robert had been listening from under the shredded couch. This is bad, this is very bad. I have got to stop scratching, it would be so embarrassing to be the only one in this tower without a weapon. He thought to himself.

The days passed without the subject being brought up again. Robert became more and more frazzled with the thought always at the forefront of his mind. Don't scratch. Don't scratch. Don't scratch. Dammit don't scratch. Don't cuss. He swore that his orange fur was turning gray from worry.

"You're not going gray" Bruce assured him.

"Are you sure? Check my tail" His voice wavering. Roberts eyes were bloodshot.

"I didn't know that cats could even get this stressed. Want a drink?" Tony offered

The physicist glared at him.

"Ok, no drink then." He placed his hands in front of him in surrender.

Many forget that Robert is only a kitten still (I know I refer to him as cat occasionally but he is roughly a year old). But that was something that Clint would never forget. One day, out of nowhere, Clint shot a suction cup arrow from the air vents and hit Robert's glasses blocking his vision. This was a declaration of war.

In the avengers tower, any act of hostility could be considered WWIII, especially if any of the A-team were involved.

Clint retreated into the vents once again as Robert fought against the suction cups. Once freed from the dark, he pursued Barton. The collar that Tony had given him on his first day there was basically the equivalent of Batman's utility belt, complete with his own cat-arang. A cat shaped shuriken shot out from his throat and headed for the section of wall that the ventilation system ran through. One of the interesting pieces of material that Robert read were the blueprints for the building.

"Shit!" Could be heard echoing down the length of the hallway, business carried on as usual, none of the agents even batted an eyelash.

Clint was pinned against the wall with the shuriken stuck between his legs, less than an inch from the family jewels.

"You were aiming there on purpose!" He accused.

"There is a wall in between us, I wasn't even sure you were in that vent, genius." Robert shot back.

Clint grumbled and loaded another arrow, this time it was a modified paint ball on the tip.

"Fire in the Hole!" A few senior agents ducked under their desks.

The arrow exploded a few feet from Robert, splashing red paint all the way down the hall, coating everyone and everything in its path. Robert looked like he just walked out of a blood bath, literally.

A very undignified shriek came from the tiny body. Hawkeye's eyes widened with fear. The kitten bounded the few feet between him and the assassin, he was out for blood. Barton let go of his hold in the vertical shaft dropping through the floor with a salute. Without any account for self preservation, Robert followed, landing on Clint's head two stories down.

They exited the vents on the main living floor. Clint was attempting to pry the kitten from his face, Robert released the itching powder from his collar into the Hawk's face.

"My eyes!" He screamed. His eyes became red and Clint resembled a wild animal rather than a human.

"I'm going to kill you, cat!"

Robert retreated onto the couch screaming "The floor is lava!"

Oh shit, now I have to find high ground fast, Clint thought. He jumped onto the coffee table.

Robert jumped onto the curtains and stuck his tongue out at his opponent.

Clint darted across the couch, leaving chalky footprints from his climbing shoes. He loosed another arrow at the ceiling, swinging to the stranded kitten.

Robert ditched the curtains for the fireplace mantle, sending family photos crashing to the ground.

Reaching the end of the mantle with nowhere else to go he screamed "TRUCE!"

The arrow on the ceiling lost its traction and sent Clint falling through the glass sculpture of Iron Man that was displayed. He made a sound that resembled a dying whale and managed a single word "~agreed~" His head rolled back.

Just then, Tony and Pepper walked in on the destroyed living room. They froze, a cup of coffee fell from Pepper's grip.

"Barton, out." Was all that Tony said.

The next day Robert was darting around the tower. Weaving in and out of desks, pausing in the corners, walking at peoples heels, anything to avoid being seen by his friends.

Bruce was walking down to the lab carrying some notes that he retrieved from Tony's office. Robert walked straight into the Doctor waiting for the elevator. He froze with fear. Bruce looked down, his eyes were immediately drawn to the kittens paws.

"Don't look at me!" Robert begged, he ran down the hall skidding around the corner.

"Tony, why are Robert's nails pink?"

"They are nail caps to keep him from scratching, they are also his punishment for nearly causing the tower to collapse."

"Harsh."

"Very" Tony pouted.

"Why are you wearing gloves?"

"Noreason" He said quickly.

Bruce snagged a glove off of Tony's hand revealing his also very pink nails.

He froze, staring at his best friend. He attempted to not laugh, but failed miserably.

"Shut up!"

"Haha now ha what haha did you do hahaha to piss off Pepper ahaha" The physicist nearly collapsed.

"It's not funny!"

"Yes it is" He said, wiping a tear from the corner of his eye.

"I just- I forgot our anniversary, Ok! This was totally undeserved and uncalled for!"

Bruce stared at the genius engineer. "You have only been married for a year!"

Tony looked like a kicked puppy, he turned away and returned to his work.
